  • Publication number: 20240072875
    Abstract: A multiple-input multiple-output (MIMO) receiver for Wireless Fidelity (Wi-Fi), and an electronic device. The MIMO receiver for Wi-Fi includes n antennas, an energy detection circuitry, a multilink gating circuitry, receiving links, a frequency offset adjustment circuitry, and a gating control circuitry. The multilink gating circuitry includes one energy detection gating output terminal coupled to the frequency offset adjustment circuitry through the energy detection circuitry and n-1 non-energy detection gating output terminals coupled to the frequency offset adjustment circuitry. The multilink gating circuitry connects each gating input terminal to one of the gating output terminals. The gating control circuitry periodically obtains a signal strength of each of the receiving links, and controls, based on the signal strength, the multilink gating circuitry to connect the gating input terminal corresponding to the receiving link that meets a preset condition to the energy detection gating output terminal.

  • Patent number: 11809986
    Abstract: A computer-implemented method for calculating a similarity between a pair of graph-structured objects by learning-based techniques. The operations include computing the node embeddings of a pair of graph-structured objects of two computer graphs utilizing a hierarchical graph matching network (HGMN). A first component of the HGMN performs graph matching of global-level graph interactions of the two computer graphs. A second component of the HGMN performs graph matching of cross-level node-graph interactions of the two computer graphs. There is an aggregating of features learned from the graph matching of the global-level graph interactions and the cross-level node-graph interactions. At least one of a graph-graph classification or a graph-graph regression is performed utilizing the learned features of the two computer graphs.

    Abstract: A system includes a plurality of graph convolutional networks corresponding to a plurality of time steps, each network modelling a graph including nodes and edges, and in turn including a plurality of graph convolution units; an evolving mechanism; and an output layer. Each of the units, for a given one of the time steps, takes as input a graph adjacency matrix, a node feature matrix, and a parameter matrix for a current layer, and outputs a new node feature matrix for a next highest layer. The mechanism takes as input a parameter matrix for a prior time step updates the input parameter matrix, and outputs the parameter matrix for the given time step. The output layer obtains, as input, output of each of the units for a final time step, and based on the output of each of the units for the final time step, outputs a graph solution.

  • Patent number: 10986087
    Abstract: A method for authenticating a user is presented. Responsive to a request for access to a computer resource, a computer system prompts the user making the request to access the computer resource to perform a new motion in an environment in which the user is monitored by a sensor system. Detected biometric data in the new motion performed by the user is identified by the computer system. A determination is made as to whether the user performing the new motion is an authenticated user based on comparing the detected biometric data with stored biometric data for a prior motion performed by the authenticated user. The computer system provides access to the computer resource when the user is identified as the authenticated user.
